Headlight opening adjusment??
On my '81, the right headlight does not go up high enough...the bulb adjusters are at their max and still the light beams hit the ground...it needs to go up a bit more. Is there an adjustment for this? Where? I found the closing adjustment...but can I adjust how far it opens? There is no actuator on this side at this time..so I know that is not what limits it.
Thanks,

You should get yourself a GM Service manual or an AIM (Assembly Instruction Manual) for detail on this and many other service proceedures.
The upward motion of the bezel is usually controlled by the actuator rod. You need to remove the springs and the cotter pin from the actuator rod and then turn or unscrew the actuator rod until it is at the proper level. There is a switch that activates a warning light if the headlamp is not fully opened. You need to make sure that it opens fully and closes the switch after you make the actuator adjustments.
It looks and sounds much simplier if you have the AIM diagrams.

Two "L" shaped brackets. One on each side. When the lights go up the hit the framing stopping the light at a certain height. Loosen them up. Lift your light to the height you want and tighten them again.

I saw the two "L" shaped brackets...but they are not hitting the frame when the light is up on either side. The lifting arm locks before they hit. Its this lifting arm that needs to be adjusted so that it raises higher before it locks. This is what I have not figured out how to adjust.
Buggys1970,
I have the Assembly Manual for my '81, not very clear. And like I wrote, I have the actuator removed, so that is not what is limiting the height. Also the warning light switch was removed in the design by '81.

I've done this adjustment but it was way back in 2004. My cars in storage so I can't even look to refresh my memory.

Done!!
Got it. There are three bolts that hold a bracket for the raising arm and the ends of two springs which has slots. I simply loosened the bolts, had to unhook the two springs...and then slid it to the other end of the slots. This gave me almost 1/4" higher...which is probably more than I need. Very easy to do, once I found the third bolt that is hidden in the center of the bracket....can't see it...but was able to feel it.
Thanks for all the help.
